Sphinx - Xylophanes tersa

Sphinx - Xylophanes tersa
Birmingham, Alabama, USA
October 2, 2007
Size: Approximately 1.4 inch
Here's another picture which might make identification easier. These guys are slow moving and find a leaf to sleep under during the day. They anchor themselves to the plants stem with thier hind legs which gave me the appearance they were about to go into a cocoon. The three I found last night all had the spike tail and had ribbed bodies which was great camoflague amongst the leafs.

Moved from Pluto Sphinx.

Moved from Tersa Sphinx.

What are they eating?
The food plant often helps pin down the ID. I'm pretty sure this is not the Tersa Sphinx, but look how similar the horn is to the one on my picture, below. I'm searching for a match in its close relatives right now. Possibly Xylophanes pluto - we don't have a larval image on this site, but compare here, particularly the image titled "Green form third instar." One more shot of its back seen from above would also help.

What are they eating?
I'll see if I have the plant tag at home but it's a flowering plant that was on "clearance" at Home Depot. It was a last minute purchase this past Spring to fill an empty spot in the garden.

I'll work on the shot from above.
